JOHN L. \(VILLIAMS, OF NEW HAVEN, CONNECTICUT.

ACID-HOLDER FOR FIRE-EXTINGUISHERS.

SPECIFICATION forming part of Letters Patent No. 719,403, dated January 27, 1903.

Application filed April 28,1902. Serial No. 105,120. (No model.)

To ctZZ whom, it may concern.-

Be it known that 1, JOHN L. WILLIAMs, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvementsin Acid-Holders for Fire-Extinguishers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to means for holding a reagent for chemical fire-extinguishers, whereby the gas-producing medium may be instantly and positively discharged, so as to produce thepressure within the tank or body of the extinguisher necessary to expel the extinguishing fluid therefrom.

The purpose of the invention is the provision of a supporting means for the bottle or other package containing the reagent which may be applied to any chemical fire-extinguisher and which will admit of the bottle or package being refilled or substituted by a new one when required.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

\Vhile the essential and characteristic features of theinvention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of the invention. Fig. 2 is a detail section showing the relation of the parts when the bottle or vessel containing the reagent has been-tilted so as to discharge its contents.

Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.

The numeral 1 represents a plug to be fitted into an opening in the upper portion of a tank 2 or other receptacle containing the extinguishing fluid. This plug is provided with opposite extensions 3 for the fingers of the hand to obtain a purchase upon when tight- A stem at passes ening or loosening the plug.

centrally through a stuffing-box 5, applied to the plug 1, and is provided at its inner end with a stopper or closure 6 and at its outer end with a handle 7. Hangers 8 are pendent from the plugl, and the bottle, package, or vessel 9, containing the chemical reagent, is pivoted between the lower ends of the hangers 8 and is adapted to be closed by the stopper 6 at the lower end of the stem 4. A flexible connection 10 connects the lower portion of the stem 4 with the upper part of the bottle or vessel 9 and is of such relative length as to admit of an upward movement of the stem to uncork the bottle 9, after which a continued upward movement of the stem effects a tilting of the bottle through the connection 10, as indicated most clearly in'Fig. 2.

The plug 1 is of a size to admit of the bottle 9 and adjunctive parts pendent from the lower side of the plug to readily pass through the opening of the tank, body, or receptacle 2, adapted to be closed by said plug when the latter is in place. It will thus be seen that access can be readily had at any time to the part 9 either for inspection, for replenishing, or for any desired purpose. When the plug 1 is removed, the bottle 9 can be easily filled and corked, the parts being placed in position with despatcli and a minimum amount of trouble. When it is required to use the extinguisher, it is only necessary to grasp the handle 7 and draw upward upon the stem 4. The first movement uncorks the bottle, and a continued upward movement of the stem tilts the bottle and discharges its contents into the tank or receptacle containing the extinguishing fluid and mixing therewith generates gas and creates a pressure which expels the extinguishing fluid in a stream from the hose-pipe in the well-known manner.

The stopper 6 is of metal, lead being preferred, and is protected by a layer or coating of rubber, which enables a close lit with the neck of the bottle being obtained and at the same time prevents the acid or other agent acting upon the body of the stopper.

The plug 1 may be of any size and in some instances may consist of a cap or cover of the tank or receptacle containing the extinguishing fluid. The size of the plug is immaterial so long as it closes the opening through which the bottle or vessel is inserted into the reserportion of the bottle, said connection admitting of a limited upward movement of the stem to unseat the stopper and upon further upward movement to efiect a tilting of the bottle to discharge the contents thereof, substantially as and for the purpose set forth.

In testimony whereof I afiix my'signature in presence of two Witnesses.

JOHN L. WILLIAMS.
